GitHub actions failing when running tests because Poetry is not installing Pandas package correctly - python-poetry

Question

This is my .github/workflows/push.yaml file:
name: Push
on:
push:
branches:
- main
pull_request:
branches:
- main
jobs:
test:
runs-on: ubuntu-latest
steps:
- name: Checkout sources
uses: actions/checkout#v3
- name: Setup Python 3.10
uses: actions/setup-python#v4
with:
python-version: "3.10"
- name: Install dependencies
run: |
pip install poetry
poetry install
python -m pip install -e .
- name: Run tests
run: python -m unittest discover tests
- name: Check code style
run: pre-commit run --all-files
These are the dependencies declared in the pyproject.toml file:
[tool.poetry.dependencies]
python = "^3.10"
pyyaml = "^6.0"
protobuf = "^4.21.12"
gspread = "^5.7.2"
openpyxl = "^3.1.0"
[tool.poetry.group.dev.dependencies]
pre-commit = "^3.0.4"
[tool.poetry.group.test.dependencies]
pandas = "^1.5.3"
I get the following error in GitHub when I push some code to my repo:
======================================================================
ERROR: test_to_xlsx (unittest.loader._FailedTest)
----------------------------------------------------------------------
ImportError: Failed to import test module: test_generic
Traceback (most recent call last):

import pandas as pd
ModuleNotFoundError: No module named 'pandas'
When I check the "Install dependencies" step log in GitHub, pandas is supposedly
being installed:
• Installing pandas (1.5.3)
However, when I add pip install pandas to my Install dependencies step, all tests are passed:
- name: Install dependencies
run: |
pip install poetry
poetry install
python -m pip install -e .
pip install pandas
----------------------------------------------------------------------
Ran 26 tests in 0.157s
OK
Obviously, I don't want to add pip install pandas like that. However, it shows that Poetry is not installing pandas correctly. What can I do in order to fix this annoying error?
PS: My poetry.lock file has the pandas package declared.
